Fizzing Colors

Turn your kitchen into a chemistry lab with this simple science experiment! You only need three ingredients: baking soda, food coloring, and vinegar. When you combine the ingredients, a chemical reaction occurs and results in a bubbling eruption of fizzing color. Acids – like vinegar – and bases – like baking soda – are special kinds of chemicals that tend to react with each other to form something completely new: carbon dioxide gas. So the bubbles you see are filled with carbon dioxide gas which creates all the foamy fizz!

  • Done!

    Use an eye dropper, pipette, or a straw to drip vinegar on top of each color drop. And voila – chemistry at work! Experiment by adding more color or vinegar. How many bubbly eruptions can you make at once?
